Safety Precautions Cut off all power supply before installation, wiring and maintenance work. Do not touch internal electrical components until waiting at least 10 minutes for complete capacitor discharge. The motor grounding terminal must be connected to reliable earth ground to avoid electric shock and electromagnetic interference. Do not apply excessive radial load, axial impact or bending force to the motor output shaft. Keep hands, tools and clothes away from rotating shaft and transmission parts during equipment running. The built-in holding brake is only used for static position locking after stopping, strictly prohibited for dynamic braking during operation. 4. Installation Instructions Mechanical Installation Install the motor on rigid, flat and vibration-free mounting base. Use standard mounting bolts and fasten evenly with specified torque. Keep precise alignment between motor shaft and load coupling to reduce vibration and bearing wear. Reserve enough space around the motor to ensure natural heat dissipation and air circulation. Electrical Wiring Use shielded cable for motor power connection, correctly connect U, V, W and grounding terminal. Adopt FANUC original matched shielded cable for encoder wiring, keep connector locked firmly. Brake shall be connected to 24VDC power supply within allowable voltage deviation, follow correct positive and negative polarity. Separate power cable and encoder cable during wiring layout to avoid signal interference. 5. Operation Instruction Operate within rated speed and torque range; do not run under long-term over speed or over load condition. It is recommended to perform low-speed jog test after power on, check forward and reverse rotation smoothly without abnormal noise and vibration. Do not start and stop frequently under heavy load for a long time. Real time monitor motor current, temperature and running status through servo driver during formal operation. 6. Maintenance Regularly check motor appearance for damage, dust accumulation and loose wiring terminals. Clean motor surface with dry soft cloth periodically. Check abnormal noise, vibration and overheating during operation every month. Inspect encoder signal stability and brake locking performance every half year. Measure winding insulation resistance regularly, ensure the value is not lower than 1MΩ under 500V test voltage. For long term storage, place in dry environment with proper temperature and low humidity, rotate motor shaft manually every three months to prevent bearing rust and sticking. 7. Troubleshooting Overcurrent alarm may be caused by motor winding short circuit, insulation damage, wiring error or excessive mechanical load. Encoder failure relates to loose connector, damaged cable or electromagnetic interference. Motor overheating is caused by long time overload, poor ventilation, bearing abrasion or mechanical jamming. Abnormal running noise usually comes from bearing aging, coupling misalignment and internal foreign matters. 8. Warranty The warranty period is 12 months from the date of purchase. Warranty covers manufacturing and material inherent quality defects. Damage caused by improper installation, wrong operation, unauthorized modification, overload use and man-made collision are not included in warranty scope.
